Event post fields and forms

Hello again!
I’m using Pods plugin to manage my taxonomies and looking for a plugin to allow guests to create posts in my webpage. Probably I’ll buy AccessPress Anonymous Post.
I would like to know how could I merge fields such as ‘dates’ or ‘places’ (of the event posts) among my other taxonomies in a ‘form-to-post’ page.
Thanks!

Sorry for all my questions!
I must say that I love the plugin and I hope to persuade the owner of the page I manage to donate something money!
